LEVI S. TAYLOR, 0F LAMOILLE, ILLINOIS.

CLEVIS FOR ATTACHING WHIFFLETREES T0 VEHICLES.

Specication of Letters Patent No.

To all whom 'it may concern:

Be it known that I, LEVI S. TAYLOR, of Lamoille, in the county of Bureauand State of Illinois, have invented a new and useful Clevis; and Ihereby declare that the following specification, in connection with theaccompanying drawings and references marked thereon, constitute a lucid,clear, and exact description of the construction and use of the same inreferring to the said drawings.

Figure l, denotes a plan or top view when in use and connected towhifletrees. Fig. 2, an inverted plan or underside view. Fig. 3, an endelevation. Fig. 4, a section of whiffletree on line A, B, of Fig. 1.Fig. 5, a section on line C, D, also of Fig. l.

[meantime- The nature of my invention consists in the clevis forattaching such whitietrees to the plow beam or other object which isconstructed with a cam catch, so that the pin after being placed thereinand simply turned, the lower end by its T shape entering a transverseoblong slot in lower part of clevis, and the upper end will come betweenthe cam and catch on upper part, which by the spring of the clevisitself, will efectually hold the pin to the clevis, and consequently thewhiffletree to the plow beam all as will be hereafter seen.

@obstruction-To enable persons skilled in the art to which my inventionappertains to construct and carry out the same I will describe it asfollows.

In order to connect this whitletree to the plow beam or other object, Iconstruct a clevis, the main part of which is seen at J and which passesthrough the central ring B, and its pin seen at I, the upper portion ofthe clevis J, has a cam O, and catch formed on and of it as seen at H,consisting in raised projections around the pin hole, and so that itcannot be got in and secured, or out, without turning it in thedirection the red arrow points in Fig. l. The pin I, near its end isnecked down, and its very-end formed T shape so as to pass through slotK, in under part of clevis, then by turning pin 26,986, dated January24, 1860.

I, this T Ypart will catch onto, and hold itself to the lower part bycoming crosswise of slot K, while the topor thumb piece of pin I, willcome in contact with cam O, and spring the two prongs of the clevistogether until the top of pin I, is moved past the cam O, and between itand the catch H, when the spring of the clevis will itself cause itsends to recoil into position indicated at Figs. l and 2, 3 and 4, the Tpart being across the slot K, as seen at Figs. 2, and 4, which willefectually hold the pin I to the clevis.

Various modications may be made of the parts and their relation to eachother, without changing the principle in the least. I4

consider the construction and arrangement shown in the drawings to bethe most simple and effectual.

Usa-All that is necessary to do in putting my within described inventioninto use is to put the clevis J, in ring B, of the whiffletree and placethe clevis upon the plow beam or other object Gr, and then put in thepin I, its top part or thumb piece at right angles from the positionseen in the drawings and turn it in the direction shown by red arrowEig. l, until it arrives past the cam O, and between it and catch H, atposition indicated in the drawings, and to remove this pin I, continuethe turning for one fourth a circle or until the thumb piece passes thecatch H, when the pin I, is readily drawn out, its T shaped lower endpassing through the slot K, formed in lower part of clevis. l

What I claim as my invention and desire to secure by Letters Patent is-My within described clevis or its equivalent device, constructedsubstantially in the manner described, and for the purposes fully setforth.
